Reinstall Qubes-Whonix ™ TemplateVMs: Stable Version
< Qubes(Redirected from Reinstall Qubes-Whonix TemplateVMs)
On occasion it is necessary to reinstall a Whonix TemplateVM from the Qubes repository. 
This chapter usually applies when the template is:
- Outdated: To upgrade to a newer Point Release or testers-only version of Whonix ™.
- Broken: TemplateVMs can become broken and/or unbootable for a number of reasons, like when removing meta-packages that Whonix "depends" on to function properly, or after mixing packages from a later Debian release.
- Misconfigured: Not all TemplateVM modifications are easily reversible. In some cases it may be necessary to reinstall the TemplateVM.
- Compromised: Users may suspect their TemplateVM has been compromised. For further information on this topic, see: Indicators of Compromise.
- Testing: To ensure a high quality of future Whonix releases by becoming a Whonix ™ tester.
The obvious reason is any TemplateBasedVMs that are based on the affected TemplateVM will inherit the same issues. Disregarding this advice could lead to serious consequences. For example, a core component of the Whonix ™ security model depends on
sys-whonix forcing all traffic through Tor or blocking it. If
sys-whonix was based on a TemplateVM with a misconfigured or broken firewall, the Whonix ™ security model would be broken. 
Qubes has its own template reinstallation guide [archive], however this Whonix ™ wiki entry should be preferred for re-installation of Qubes-Whonix ™. The reason is this guide is Whonix-specific and contains instructions on how to properly configure all settings. 
Use one of the following methods:
- A) Uninstall Qubes-Whonix ™ and then Install Qubes-Whonix ™; OR
- B) Follow the Reinstall the Whonix TemplateVM instructions below.
Reinstall the Whonix TemplateVM
Since only Fedora-based UpdateVMs support the
--action=upgrade option for reinstalling the TemplateVM, it is recommended to create a dedicated Qubes
dom0 UpdateVM based on Qubes' Fedora template. Forcing
dom0 updates over Tor is still possible by setting
sys-whonix as the NetVM for the UpdateVM. 
Click the Qubes App Launcher (blue/grey "Q") →
Open the Terminal Emulator (Xfce Terminal)
dom0. This step is mandatory. 
Configure salt using Qubes dom0 Community Testing Repository
If you are a tester interested, click on Expand on the right.
The following command will configure Qubes
dom0 salt to use
qubes-templates-community-testing for downloading Whonix ™. 
sudo qubesctl top.enable qvm.whonix-testing pillar=true
The following steps to enable the
qubes-templates-community-testing repository should no longer be required. Please report if these steps were necessary for you.
If you are a interested tester, click on Expand on the right.
Adjust Whonix Version Number
This step can be skipped on Qubes
4.0.2 and above when installing Whonix ™ 15.
Please report if this step was necessary for you!
In the instructions below, a check is first made for a newer version of the TemplateVM.
- If a newer TemplateVM version exists, install it (
- If no newer TemplateVM version is available, reinstall the existing version (

salt to configure
dom0 settings. 
sudo qubesctl state.sls qvm.anon-whonix

sudo qubesctl state.sls qvm.whonix-ws-dvm
Updates over Tor
To force all TemplateVM updates over Tor,  use salt in
sudo qubesctl state.sls qvm.updates-via-whonix
To undo this setting, modify
dom0.  See also How-to: Fix dom0 Qubes-Whonix ™ UpdatesProxy Settings.

dom0 UpdateVM to
sys-firewall or another preferred VM. 
If you are interested, click on Expand on the right.
The following steps should be completed in
dom0 for both
whonix-ws-15 TemplateVMs.  After these settings are applied to the Whonix ™ templates, the
sys-whonix (ProxyVM) and
anon-whonix (AppVM) will inherit the AppArmor kernel settings.
It is unnecessary to recreate the
anon-whonix TemplateBasedVMs to benefit from the new kernel parameters. It is also important to verify AppArmor is active in the
anon-whonix VMs after making these changes.
Any VMs based on the reinstalled TemplateVM must be restarted to reflect the updated file system.
Update and Launch Applications
Before starting applications in the Whonix-Workstation ™ AppVM, update both Whonix-Gateway ™ and Whonix-Workstation ™ TemplateVMs.
To launch an application like Tor Browser:
The process to reinstall Qubes-Whonix ™ TemplateVMs is now complete.

This is because the name of the TemplateVMs changed from:

dom0UpdateVM is based on a template that is broken or no longer trusted (the template is broken, misconfigured or compromised), an alternate UpdateVM can be used temporarily. In other words, more specifically, if the Whonix-Gateway ™ TemplateVM (
whonix-gw-15) and/or its Whonix-Gateway ™ ProxyVM (
sys-whonix) are no longer trusted, then configure Qubes
dom0to use a different UpdateVM by applying the following steps. TODO

To revert this change in
qubes-prefs updatevm sys-firewall
While Debian has enabled AppArmor by default since the
busterrelease, Fedora has not. This matters since Qubes, which is Fedora based, by default uses the
dom0(not VM) kernel. Therefore this is still required even though Whonix ™ is based on a recent enough Debian version.
- Since Qubes R3.0, TemplateBasedVMs inherit the kernelopts setting of their TemplateVM [archive].
